To all whom it may concern: l Be it known that I, Isnnonn PoMnnANTz, a citizen of the" United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certainnew and useful Improvements in Lintel- Blocks* and I do declare the following to be a full, clear, and exact description ofv the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the A. accompanying drawings, and to the letters and figures of reference marked thereon,

which forni a part of this speciiication..

My invention relates to improvements in blocks and more particularly to a sembled with blocksl of like construction to form a mold for receiving a plastic building.`

material whereby a monolithic lintel slab may be formed to" support a brick, or other wall, across a door or window opening.

"lhe principal object of the invention being to provide blocks of this character that maybe used in place of the usual Wood or I-beam lintel and whereby a tight and weather-proof joint may be made with the `upper edge of the window or door frame above which the lintel is formed'.

'It is also 'an object of the invention to provide blocks of this character wherein nailing strips may be located for receiving nails, screws, or other anchoring devices for the support of molding, etc., on the inner face of the lintel.

In accomplishing these objects I have provided improved details of the structure, the preferred forms of which Vare illustrated in the accompanying drawings; wherein: Figure I is an elevation of a part of a building Wall showing a window lintel constructed of blocks formed and assembled according to the present invention.`

Referring Vmore in detail tothe drawings: l

1- designates a building wall or;the like having a window opening '2 therein across which a lintel, comprising building blocks 3 formed and assembled according to the 'pres-v *Y ent invent-ion, is located.

Each of the blocks in the preferred form l l of construction, is `substantially rectangular in cross sectionand comprises-an under side `or base wall 4:, a double outer'wall 5 forming an air chamber 6, and a correspondinglyv heavy inner face wall'7 spaced therefrom having an air chamber 9 formed along its upper edge. The ends and upper side of the block being open so that when a pluralityof s uch blocks are arranged end lto end,

a continuous upwardly opening channel is formed, wherein a plastic material 10, such as building cement, may be oured; and which after it has set, will monolithic slab within the blocks-whereon -a wall may be built andthereby supported above the wall opening,

If it is necessary ordesired reinforcing rods 1l, as shown in Figs.v -II andIV may be embedded in the. cement to substantially strengthen lintels of unusual len-gt Each of the blocks is provided on its under face and adjacent its forward edge with a longitudinally extending groove or slot 13.an d when the blocks are arranged in functional relation these grooves will forml 'a continuous channel wherein the stop 1.4: in a window'or -like frame 15, that isl located within the opening, maybe inserted, as is particularly shown -in Figs. II .and V, toV form a perfectly tight joint between the lintel and frame. y f f The blocks are likewise provided in their inner. walls with longitudinally arranged dovetail groove 16 for receiving wood or other nailing strips'll'?, Whereto window or door casings, moldings, ete., may be anchored. Such strips being inserted wheref necessary 'before the blocks are placed in' position. Q In Fig. V I have shown a modified form of block Which is adapted for use 'where it is desired to shoW a stone faced lint-el. ,In

extending. horizontal shelf 18 is formed orm a solid 'ioo 11o a longitudinally A firmly in place.

If itis necessary, the 'block walls, back of the slots formed-therein, may be reinforced as is ,shown at 21 in Fig. III and at 22 and `23`in Fig. V, so that the' vslots will in no way weakenthe construction of the block.'

In Fig. VI' I have illustrated the' use of anchor members between the adjacent ends of blocks arranged as described. The anchor members 25 used preferably comprise single strips ofinetal, bent. dou le toform thin clips. which may be'A located 'within the joints between adjacent ends of blocks, withA their outerends turnedlaterally to lie flush with the inner faces of the blocks and their A inner ends -en'ihedded in the cement to anchor the clips in place. Anchor -oigxiailng` strips 28 may be fixed to clips of thischracter by driving nails Ithrough the strips and between tightly against the nails andhold the strip When blocks of this character come fro the pressing mold, they comprise top Walls 30 as is 'shown in'Fig. VII. These top walls serve t0 retain the blocks in'` shape until they have been burned or. baked in'a kiln, then the top walls or panels 30, which are scored as shown at ISL-31', when the block is soft,

are broken away without injury to the other'.

parts .of the/block and tle channel` member remains intact. o,

`When a lintel is .tobe built of blocks -conl' structed according to the present invention, the window or door frame is first located in the opening and the blocks arranged -in proper relation across the top thereof and' resting on the frame with thestop` at the' top of the frame seated in the under face groove of ltheV blocks. vConcrete is then poured into .the channel iormed by the blocks and, if -it isneccssarygor desired, re-

inlforcing rods are embedded ther-eilig. so that w-hen theconcrete sets, a substantially Solid block of suliicientstrength is formed across the window` to supportthe usual brick or stone wall.. f I.

If novfacing is tobe used in front ofthe blocks, they are placed flush with the outer face "of thewall as shown 'in Fi'gf I, 'but -should it be desired to face the wall with a `stone slab as shown in Fig.' V, the. lintel Ablocks are set back, far enough that when' the slab is placed in position it will be flush the side inenibers of theV clips which bind with the outer face'ofthe finished wan.

solid slab support, the building wall may then be constructed across the lintel in the usual manner.

It'isapparent that by) so constructing the blocks a-lintel may be formed that 'will eliminate the' use of the usual'I-bcam or WOOd lntelS, a less expensive construction 'is provided, and-a more attractive' result is than `those. shown could be provided for the same purpose without, departing from vthe lar types shown; l

Havingr thus described. my invention what .c I claim as new thereixib'and wish to secure by Letters Patent, is;

' 1. In a buildingr havin'q an opening, the

combination' with afrau'ie in the opening,

of a 'plurality of lintel blocks vupoil the framerarranged `end to end and each block comprlslng abottom and ltwo lip-standing side Walls,a stopstrip on'the frame and extending into the lintel blocks to seal the joint between the lintel yblocks and thc frameynailing strips keyed in the rear walls of the lintely blocks and vertical strips connected to the nailing strips and. bearing against the rear face of th'e frame.

2. In a building, having an openingiglthe combination with a frame in the opening, of

a plurality of lintel blocks upon the trame prising a bottoni and two lip-standing side walls, a stop striiion the frame and. extend 'ing` luto. the lintel blocks to seal the 4joint.
